Window Unit Oversize?

Hey guys, my room mate is looking to buy a window unit for his room and he is asking why he shouldn't over size it. I told him that it will short cycle, which will not dehumidify, drop efficiency, and the unit won't last as long. He's wondering if he just drops the tstat to like 60 or something the unit won't pull down to wouldn't that work just as well? I'm not a 100% but I think the evap will freeze if there is no off cycle but I want to give him the correct answer. I'm still a student and still learning. Any help/feedback is much appreciated. Thanks

A little oversized on a window shaker won't hurt anything. Running all the time won't hurt it either. If he's in college and dumb enough to set the stat at 60 degrees and it freezes up - hmnn ???

Why is it that 90&#37; of people think an air conditioner will get cooler faster if they drop the thermostat way below the desired temp? The thermostat has nothing to do with capacity. It tells the unit when to start and stop and nothing else.

Thanks for all your help. I'm going to tell him to go for it and get the bigger one. If it does keep short cycling he just needs to open his bedroom door and share some of the cold goodness. I'll make sure he doesn't turn the tstat that low, it was just as an example. Thanks again.

How much to look at my window unit?

I was working in the office today for a bit and a lady called up and asked me how much it would cost for us to come out and look at her window unit, I should of said just toss it and buy another, but I simply said, sorry we do not service them. Who does service them? I can't see a small window unit even being fixed most cheapos go for around xx dollars at walmart.

dummy.

take the service call. diagnose it and tell her its cheaper to buy new one.

And that you will dispose of old one properly.

then either fix it for a loaner or recover the precious R-22 and scrap the rest for recycling (gas money)

If you don't know, then don't do. If you don't know and still do, then be prepared to pay someone else a lot to undo what you did and then do it right.

If you do know, then do. But do it right. Otherwise, you may not be doing it long.
